Given a binary grid representation of a map of an island, calculate the perimeter of the island. The grid uses '0' for water and '1' for land.
The grid has only one i...
Calculate the perimeter of an island represented by a binary grid.
Iterate through the grid and count the perimeter based on land cells and their adjacent cells.
Each land cell contributes 4 units to the perimeter, subtract 2 units for each adjacent land cell.
Handle edge cases where land cells are at the boundaries of the grid.
Return the total perimeter for each test case.

The test link was active for a week, and you can give anytime you like. The IDE was very good and self explanatory. There were 2 coding questions and 15 aptitude questions.
You are tasked with finding the shortest path between two houses in the city of Ninjaland, represented as an unweighted graph. The city has N
houses numbered from 1 ...
Find the shortest path between two houses in a city represented as an unweighted graph.
Use breadth-first search (BFS) algorithm to find the shortest path in an unweighted graph.
Start BFS from the source house and keep track of the path taken to reach each house.
Once the destination house is reached, backtrack from destination to source to find the shortest path.
Consider using a queue data structure to implement BFS eff...
You are given an arbitrary binary tree consisting of N nodes, where each node is associated with a certain value, and two node values, a
and b
. Your task is to determine if ...
Check if two nodes in a binary tree are cousins by comparing their levels and parents.
Traverse the tree to find the levels and parents of the given nodes.
Compare the levels and parents of the two nodes to determine if they are cousins.
If the levels are the same and the parents are different, the nodes are cousins.

A complete binary tree is defined as a binary tree...
Count the total number of nodes in a complete binary tree given its root.
Traverse the tree in level order and count the nodes
Use a queue to keep track of nodes at each level
Check for null nodes represented by -1 in the input
The total number of nodes in the example tree is 7
Given an array ARR
consisting of non-negative integers, rearrange the numbers to form the largest possible numerical value. You are not permitted to alt...
Rearrange array numbers to form the largest possible numerical value by combining digits of each number in the array.
Convert integers in the array to strings for easier manipulation.
Sort the array of strings in non-increasing order based on custom comparison function.
Join the sorted strings to form the largest possible number.

This was more of a interaction round with some technical skills.
ACID properties ensure database transactions are processed reliably. Rollback mechanism undoes changes if transaction fails.
ACID properties: Atomicity, Consistency, Isolation, Durability
Atomicity ensures all operations in a transaction are completed successfully or none at all
Consistency ensures database remains in a valid state before and after transaction
Isolation ensures transactions are independent and do not inter...
Tip 1 : Focus on different varieties of problems, quality of problems matter greater than the quantity.
Tip 2 : Focus on design thinking, that will help in rounds other than problem solving.
Tip 1 : Focus on demonstrating your academic excellence and course projects
Tip 2 : Mention internship details with clarity

I was shared a link of Google Meet and the Google Docs was shared where there was 1 coding problem to be coded there and then the code was run on an IDE to check the sample tests.
Then the interview was followed by a lot of Operating System and Computer System Architecture Questions.
There were 2 Interviewers and both were helpful.
The timing was from 2:30 PM to 4:00 PM
Determine the length of the largest subarray within a given array of 0s and 1s, such that the subarray contains an equal number of 0s and 1s.
Input beg...
Find the length of the largest subarray with equal number of 0s and 1s in a given array.
Iterate through the array and maintain a count of 0s and 1s encountered so far.
Store the count difference in a hashmap with the index as the key.
If the same count difference is encountered again, the subarray between the two indices has equal 0s and 1s.
Return the length of the longest subarray found.
Round duration - 45 minutes

The round was held on Google Meet with HR from 2:30 PM to 3:15 PM.
The HR was friendly and asked the basic questions.
Tip 1 : Practice daily 4-5 medium level problems on sites like Leetcode, CodeZen, Hackerearth
Tip 2 : Even though Data Structures and Algorithms is the base but study Course Subjects like DBMS,OS,OOPS too.
Tip 3 : Try to Participate in Contests on LeetCode,Codeforces.
Tip 1 : Mention the projects you worked on in your past work experience and how it helped your company.
Tip 2 : Keep your resume up to date in accordance with the role you are applying for
Tip 3 : Don't put false things on your resume.
